Definitions

  • This invention relates to a system in which an additive is mixed with fuel for delivery to an engine.
  • the exhaust system of a diesel engine may be equipped with a trap to separate particulates from the engine exhaust gases and thereby reduce emission of particulates into the atmosphere. Such a trap must be regenerated periodically.
  • Some proposals for trap regeneration involve use of an additive in the fuel consumed by the engine.
  • the additive passes to the trap in the engine exhaust gases, it catalyzes combustion of the particulates in the trap and thereby facilitates regeneration of the trap.
  • This invention provides a fuel additive metering system by which an additive is mixed with the fuel delivered to an engine in an amount proportional to the amount of fuel consumed by the engine.
  • fuel is drawn from a reservoir, a portion of the fuel is delivered to the engine, excess fuel is directed back to the reservoir, fuel is supplied from a tank to the reservoir to maintain a constant volume of fuel in the reservoir, the amount of fuel supplied from the tank to the reservoir is measured, an additive is fed to the reservoir for mixing with the fuel, and the rate at which additive is fed to the reservoir is proportioned to the rate at which fuel is supplied from the tank to the reservoir, whereby the amount of additive consumed by the engine is proportioned to the amount of fuel consumed by the engine.
  • FIGURE is a schematic view of a preferred embodiment of the fuel additive metering system provided by this invention.
  • a fuel system for a diesel engine includes a fuel injection pump 10 that draws fuel from a reservoir 12 through a line 14, a filter 16 and a line 18, delivers a portion of the fuel to the engine 20, and directs excess fuel through a line 22, a fuel cooler 24 and a return line 26 back to reservoir 12.
  • a supply pump 28 delivers fuel from a tank 30 through a line 32, a water separator 34, a line 36, a fuel metering unit 38 and a line 40 to reservoir 12.
  • the inlet from line 40 to reservoir 12 is controlled by a float valve 42 to maintain a constant volume of fuel in reservoir 12.
  • Fuel metering unit 38 has an inlet 44 that receives fuel through line 36 from pump 28, and an outlet 46 that directs fuel through line 40 to reservoir 12.
  • a valve 48 alternately allows fuel to flow into unit 38 through inlet 44, and to flow out of unit through outlet 46. With valve 48 in the position shown by solid lines, pump 28 causes fuel to flow through inlet 44 to a chamber 50 closed by a diaphragm 52. The fuel raises diaphragm 52 against the bias of a spring 54 until a shaft 56 carried by diaphragm 52 closes a switch 58.
  • controller 59 When a controller 59 senses closure of switch 58, it energizes a solenoid 60 to move valve 48 from the solid line position to the position shown by dotted lines. The bias of spring 54 then lowers diaphragm 52 and causes fuel to flow from chamber 50 through outlet 46 to reservoir 12 until shaft 56 closes a switch 62. When controller 59 senses closure of switch 62, it deenergizes solenoid 60 to move valve 48 from the dotted line position to the solid line position. Pump 28 then causes additional fuel to flow through inlet 44 to chamber 50
  • a positive displacement pump 64 feeds additive from a tank 66 through a line 68 and a check valve 70 into return line 26 and thus to reservoir 12 where the additive mixes with the fuel.
  • a controller 72 operates additive pump 64 in response to operation of switch 62, proportioning the rate at which additive is fed to reservoir 12 to the rate at which fuel is delivered by supply pump 28 to reservoir 12, and thereby proportioning the amount of additive delivered to engine 20 to the amount of fuel consumed by the engine.
  • the fuel additive metering system provided by this invention thereby creates a precisely proportioned blend of additive and fuel for delivery to the engine.
  • the fuel additive metering system provided by this invention also assures that the additive will not come into contact with fuel that contains water. Any water that may be present in the fuel delivered from tank 30 is separated in separator 34 so the additive may be mixed with water-free fuel in reservoir 12.
  • the fuel additive metering system minimizes the time during which the additive must remain mixed with the fuel.
  • the additive is mixed with fuel in a minimum volume portion of the fuel system, and the residence time of the additive in the fuel is minimized accordingly.
